/* design-system: page-library v1 | tokens.css */
/* Token sheet for the page library: three tiers, and nothing else.
 *
 * This banner deliberately does not name the file. The fleet linter treats a first line that
 * names tokens.css/base.css as a COPY of the canonical fleet system, which this is not: it is a
 * second vocabulary with its own names. Claim "copy" and the linter correctly demands it match
 * the fleet, and 212 findings follow. See NOTES.md, "A fork, not a copy".

WHY THREE TIERS
Tier 1 is raw value. Tier 2 is a role a product may use. Tier 3 is a component's own
decision. A component may read tier 2 or 3 and never tier 1, which is what stops a page
from picking a specific grey. The build fails on a tier-1 read outside this file.

WHY THE NAMES ARE ROLES, NOT HUES
`--ok` survives a rebrand and `--green-600` does not. The only hue-named tokens here are
tier 1, which nothing outside this file may use.

WHY HEX AND NOT OKLCH
oklch() is the better authoring space and it is Baseline. It is not here yet because the
contrast gate parses hex, and a token layer the gate cannot measure is a token layer the
gate cannot protect. That is a stated trade, not an oversight: see NOTES.md, D3.
